Marine weather data you can trust

Our network of marine weather sensors provides real time confidence and reduces forecast uncertainty by up to 50%.

The most accurate marine weather forecast. Anywhere.

Marine weather forecasts have been unreliable because they lack accurate real-time data. Our privately-owned network of open ocean sensors fills this data gap and reduces uncertainty in marine weather forecasts by up to 50%. A few lines of code give you more accurate real-time conditions and the best forecasts across our world's oceans.

What Makes Our Data Unique

Real-time Sensor Network

We build and deploy our own marine weather sensors, which allows us to maintain and operate the largest privately-owned marine weather sensor network in the world.

Our network provides unprecedented access to real-time ocean weather data and makes the Sofar Marine Weather Forecast better than any other.

Data-Driven Solutions

Data is the key to better weather forecasts. To get all our data into our models, we use the latest advances in data-assimilation strategies and machine learning.

Our models already reduce forecast uncertainty by up to 50%. And we continue to improve our data-assimilation strategies every day.

Get Started

Flexible API

Our goal is to make access to ocean data easy. Our API is designed to provide seamless integration of our data into your products and offerings.

We currently offer three different API packages.

Marine Weather API

Access to the best marine weather forecasts anywhere in the world.

Wave Spectra API

Access to 16-day forecasts of 2D wave spectra anywhere in the world.

Spotter Sensor API

Access to our global network of Spotter buoys, both real-time and historical.

Collect your own data? Check out our ocean tools

We are passionate about enabling you to collect ocean data and explore the underwater world. Our ocean tools are built to last, designed for usability and affordability, and validated to provide high-fidelity ocean data.

Spotter

Get real-time marine weather data anywhere.

Wind, Wave, and Temperature Data

Spotter collects 3D displacement time series and water temperature data. The 2D wave spectrum, surface wind velocity, and Sea Surface Temperature (SST) are calculated and stored onboard, and user-selected data is transmitted through satellite to the Spotter Dashboard.

Compact & Portable

Spotter can be shipped anywhere around the world, carried by hand, and deployed without any special equipment.

Solar Powered

Self-contained, low maintenance, and always ready to go.
